Trying to grow bay laurel outdoors in south florida. Started with a six inch plant and now two years later it has five shoots from ground level and the tallest is 20 inches. The new shoots and leaves are beautiful but when the leaves get to be about three months old they start turning brown at the tips and progress to brown about half way back. And the older leaves even if not brown look bad and not very appetizing. Is it natural for the leaves to have a short lifespan of a few months? At the stem where the leaves are attached it looks like another leaf bud. If I pick off the old leaf will a new one grow from the bud at the same spot? And should I harvest the leaves and dry them before they get to looking bad?
